IMPROVED POLE roe HORSE RAILWAY cans. I

SPECIFICATION.

TO ALL WHOM IT MAY CONCERN: j Be it known that I, DANIEL T. ROBINSON, of Boston, in the countyof Sufi'olkand State of Massachusetts,

have invented an improvement in Poles of Horse Railway Cars; and Ido hereby declare that the following,

taken 'in connection with the drawings which accompany and form part of this specification, is a descripti'on of my invention sufficient to enable those skilled in the art to practise it.

In applying poles to horse railway cars, it is customary to fasten the pole to the platform by a'loose coupling bolt, passing through a coupling plate or bar fixed to the pole, and a bolt-eye fixed to the platform, and to sustain the bolt at a properv horizontality by a brace bar (lxtending'from the under side of the pole, at, a short distance from its rear end, down from the bar and back to the plane of the bolt hole, and so as to abut against and straddle a bolt or rod attached to the car platform, thereby bracingnp the bar or keeping it fromdrawing f down upon the horses. By wear of the end of the brace bar against the bolt, however, or from othencauses,

the pole soon sags and gets out of horizontal position. To obviate orcounteract this dcfcct or liabilityislthe object of my invention, which consists in so connecting this brace at its rearend to the pole, that its bolt- 3 straddling and abutting end may be adjusted or fed forward as occasion mayrequirc, to determine the position of the pole or keep it from undue sagging. A The drawings represent a pole cmbodyingthe invention; A showing a side view, and a reversed plan of the same.

adjusting nuts, '1', play, as will be readily understood. Now, it will be obviousthat the position of the frontend,

of. the brace-bar may be dcterminedand variedby means of these nuts arid screw and the projection 9, so that, 1 as the bolt-abutting slot in'the brace becomes worn, or the pole, from other causes, sags down, the pole may be i brought back to proper position by lowering the front nut 2', and! tightening the rear one, and that, by a little i care, the proper horizontality of the pole may thus-be always maintainer1..,

I claim combining with the pole a, coupling plate or bar 6, and brace rod or bar a, the means oninechanism;

for adjusting the position of this brace b'a-r relatively tothe pole, substantially asset forth.
